Patent number: 11674491Abstract: Systems and methods of providing fault protection on direct current (DC) feeds to various engine or generator set components are provided. In some embodiments, generator set includes a ground fault device arranged between a DC power distribution circuit and a subsystem of the generator set. The ground fault device is configured to detect a fault condition based on a comparison of a first current in a first wire with a second current in a second wire between the DC power distribution circuit and the subsystem. In response to detecting the fault condition, the ground fault device is configured to disconnect the subsystem.Type: GrantFiled: July 7, 2022Date of Patent: June 13, 2023Assignee: Cummins Power Generation Inc.Inventors: Lane Woodland, Randall J. Johnson, Sagar Sharma, Elias M. Ayana, Michael Fegley
